<div class="textblock"><p>The Xilinx DFX axi shutdown manager driver can be used to provide a boundary between the static logic and a Reconfigurable Partition during Partial Reconfiguration.The Xilinx DFX AXI Shutdonw manager supports below features Multiple Options for Status and Control: The DFX AXI Shutdown Manager core can be controlled and queried using single signals or an AXI4-Lite interface. Dynamic Function eXchange Controller Core Interoperability: The DFX AXI Shutdown Manager core connects directly to the Dynamic Function eXchange Controller core using the signal based control interface.</p>
<p><b> Initialization and Configuration </b></p>
<ul>
<li>XDfxasm_LookupConfig(DeviceId) - Use the device identifier to find the static configuration structure defined in xdfxasm_g.c. This is setup by the tools. For some operating systems the config structure will be initialized by the software and this call is not needed.</li>
<li><a class="el" href="group__dfxasm.html#gadfe5b93b82691e4bb3318a18e9e46724" title="This function initializes a XDfxasm instance/driver. ">XDfxasm_CfgInitialize()</a> is used for initialisation. The user needs to first call the <a class="el" href="group__dfxasm.html#gae65186e7648d1f958994314c58c674d5" title="This function looks for the device configuration based on the unique device ID.

</ul>
<p><b> Threads </b></p>
<p>This driver is not thread safe. Any needs for threads or thread mutual exclusion must be satisfied by the layer above this driver.</p>
<p><b> Asserts </b></p>
<p>Asserts are used within all Xilinx drivers to enforce constraints on argument values. Asserts can be turned off on a system-wide basis by defining, at compile time, the NDEBUG identifier. By default, asserts are turned on and it is recommended that users leave asserts on during development.</p>
<p><b> Building the driver </b></p>
<p>The XDfxsm driver is composed of several source files. This allows the user to build and link only those parts of the driver that are necessary.</p>
